8.8" Polished Petrified Wood (Woodworthia) Section - Arizona

This is a 8.8" wide, polished round section of petrified wood (Woodworthia) from the Chinle Formation of Arizona. Woodworthia is one of the more uncommon types of petrified wood within the petrified forests of Arizona. The polishing work on this piece is fabulous and it comes with a display stand.

The thickness of the specimen isn't consistent across the entire petrified wood section due to portions of the wood missing. Its thinnest point is .25", with the thickest portion measuring 2.5" thick. There are natural fractures throughout the specimen, one of which looks to have been stabilized with glue (when viewing specimen from the backside).

Petrified wood is the name given to wood that has been turned into stone (fossilized) through the process of permineralization. All of the organic matter becomes replaced by minerals, while much of the original structure such as tree rings in retained. For this to happen the wood needs to be buried in an environment both low in oxygen (preventing decomposition) and with flowing, mineral-laden water. The coloration is due to the various minerals that are present during fossilization. For example red colors are due to iron compounds, greens due to copper, etc.
